Wikipedia

Every time I visit Wikipedia it's changed - there's been a new layout or a new category of information.

Just as you think the world is getting smaller, when you can chat with friends in Australia on facebook and find friends you haven't seen in years, Wikipedia makes you realise how big the world actually is!

I'm a bit nervous about editing something in Wikipedia, so haven't done that yet, but if I do see something that needs correcting I know I can do this now thanks to 23 things!
